Nasty noises on the 501 : ( and maintenance issues

[Colinevan]

Well my 501 wasnt very nice to run today, i had a few noise issues that appeared to be coming from the diffs. To eliminate the probs i tried the 1 way, then swapped back and finally replaced back with the 1 way lol. I then checked the rear diff. ( i was a busy guy as i was also running the rb5 in 2wd ...5 races and 4 heats per car and 2 finals lol so not much time spare lol ) which was the usual diff moan lol.

So far iv found that the new ceramic diff balls havnt really made the diffs any quiter or smoother. When i stripped the diffs down they wasnt particularly bad and the diff rings had only slight markings that you couldnt really feel, just see where the balls were running. I checked all the belts and the pulleys.. Hmm only last thing .. the slipper.

With the rear wheels held tightly, i then span the motor up via the tx and the noise was the same squeeling that iv heard on both jmmy's and stu's. cars. Does anyone else have slipper squeels... they sound like metal binding and squeeling. i think the pads will also want replacing now.


I have also decided to relpace the diff rings as a precaution, hmmmm Hobby company are quoting theyre usual 6 - 8 weeks so i guess im going to go abroad again. has anyone replaced these yet. If so, where did you get them from?

Lastly i also noticed the pins in the axles(the pins that hold the axle to the dogbone with the cross piece and grub screw )were all out of place slightly, the grub screws that hold them in were still tight but the pins all seem to have moved. They were rubbing against the hubs slightly , so be warned and check yours.

Is there anything else i need to look out for?

Thanks
